The experimental study of the transonic equivalence rule with lift, has been extended to include a configuration of swept-back wing-body and the corresponding equivalent bodies for lift and zero-lift. For zero lift, the wing-body is shown to have higher wave drag than that of the equivalent body. At lifting condition, the analyses of the data, including those of the delta wing-bodies have verified the similitude of drag rise due to lift between the wing-bodies. The additional drag induced by the effective area due to lift between the wing-bodies. The additional drag induced by the effective area due to lift on the equivalent body was found to agree reasonably with the wave drag generated by lift on the wing-body. The experiment thus verified the area rule with lift which must be considered in the optimal design of transonic configurations.
